    Complete the analogy. Brown eyes are dominant. 

    • Recessive:Dimples

    • Recessive: blue eyes

    • Recessive: being funny

    • Recessive: Number of bones in your body

    Correct Answer
    A. Recessive: blue eyes
    Explanation
    The analogy is based on the concept of dominant and recessive traits. Brown eyes are considered dominant because they are more likely to be expressed in an individual's phenotype. Similarly, blue eyes are considered recessive because they are less likely to be expressed. The analogy implies that just as brown eyes are dominant over blue eyes, there is a similar relationship between the other listed traits. Therefore, the correct answer is "Recessive: blue eyes."

    All of the following are phenotypes except:

    • Eye color

    • Attached Ear lobes

    • Personality

    • Height

    Correct Answer
    A. Personality
    Explanation
    Phenotypes refer to the observable characteristics of an individual that are influenced by both genetic and environmental factors. Eye color, attached ear lobes, and height are all examples of phenotypes as they can be observed and measured. Personality, on the other hand, is not directly observable and cannot be easily measured. It is a complex trait that is influenced by a combination of genetic, environmental, and psychological factors. Therefore, personality is not considered a phenotype.

    Heterozygous traits are revealed in genotypes:

    • AA

    • Aa

    • AA

    • Aa

    Correct Answer
    A. Aa
    Explanation
    Heterozygous traits are revealed in genotypes when there is a combination of two different alleles for a particular gene. In this case, the genotype Aa represents a heterozygous trait because it contains both the dominant allele (A) and the recessive allele (a). The presence of both alleles allows for the expression of both traits, resulting in a heterozygous phenotype.

    From the picture above of parents, infer what charateristics might their children have? - ProProfs

    From the picture above of parents, infer what charateristics might their children have?

    • They will look exactly like thier parents

    • They will have long hair

    • The children will have at least 75% of having brown eyes

    • They will have dimples

    Correct Answer
    A. The children will have at least 75% of having brown eyes
    Explanation
    Based on the given picture of the parents, it can be inferred that their children will have at least a 75% chance of having brown eyes. This suggests that brown eyes are a dominant trait in the parents and are likely to be passed on to their offspring. However, it is important to note that this is not a guarantee, as there is still a possibility for other genetic factors to influence the eye color of the children.

    Find the answer that best fits: Asexual organisms:

    • Have the ability to copy themselves

    • Are very complex and higher order animals

    • Lay eggs

    • Are only plants

    Correct Answer
    A. Have the ability to copy themselves
    Explanation
    Asexual organisms have the ability to copy themselves through a process called binary fission or budding. This means that they can reproduce without the need for a mate or sexual reproduction. They can create genetically identical offspring, which is a form of cloning. This ability allows asexual organisms to rapidly increase their population size and colonize new environments. Unlike sexual organisms, asexual organisms do not need to invest energy in finding a mate or producing specialized reproductive cells. Instead, they can simply divide and produce offspring that are exact copies of themselves.

    In sexual reproduction, organism have either:

    • A male cell or female cell

    • A nucleus or a nucleolus

    • Chromosome or alleles

    • The ability to copy themselves

    Correct Answer
    A. A male cell or female cell
    Explanation
    In sexual reproduction, organisms have either a male cell or a female cell. This is because sexual reproduction involves the fusion of gametes, which are specialized cells that carry genetic information. The male cell, known as sperm, is produced by males, while the female cell, known as an egg or ovum, is produced by females. During fertilization, the male and female cells combine to form a zygote, which develops into a new organism. This process allows for genetic variation and the mixing of traits from both parents.

    If your grandparents all had dimples and your parents all have dimples which statement is true?

    • None of the children will have dimples.

    • Dimples are not passed down through heredity.

    • All your brothers and sisters will have dimples.

    • Nature causes dimples you cannot predict when someone will have them.

    Correct Answer
    A. All your brothers and sisters will have dimples.
    Explanation
    If both your grandparents and parents have dimples, it suggests that the trait for dimples is dominant in your family's genetic makeup. This means that if you have siblings, all of them will likely inherit the gene for dimples and therefore have dimples as well.

    Homozygous traits are revealed in genotypes that are:

    • Different

    • Same

    • Traits that are recessive

    • Traits that are dominant

    Correct Answer
    A. Same
    Explanation
    Homozygous traits are revealed in genotypes that are the same. This means that both alleles for a particular trait are identical. In a homozygous genotype, both alleles can be either dominant or recessive. When both alleles are dominant, the trait will be expressed in the phenotype. Similarly, when both alleles are recessive, the recessive trait will be expressed.

    What information would you need to have in order to analyze whether or not the Obama children could have blue or green eyes? - ProProfs

    What information would you need to have in order to analyze whether or not the Obama children could have blue or green eyes?

    • Their blood type

    • What the grandparents genotypes and phenotypes were.

    • They would not be able to have blue eyes

    • All of their eyes will be brown

    Correct Answer
    A. What the grandparents genotypes and phenotypes were.
    Explanation
    To analyze whether or not the Obama children could have blue or green eyes, it is necessary to know the genotypes and phenotypes of the grandparents. Eye color is determined by multiple genes, so knowing the genetic makeup of the grandparents would provide information about the possible combinations of genes that could lead to blue or green eyes in the children. Without this information, it is not possible to make any conclusions about the potential eye color of the Obama children.

    Mrs. Cobble has two guinea pigs, one black male and one white female.  They have babies, 2 are white, and 5 are black.  Why?

    • Male guinea pigs are dominant

    • Parents traits do not matter, nature decides.

    • Black guinea pigs have more traits than white guinea pigs.

    • Guinea pigs get have of their traits from mom and half from dad. Some traits are recessive some are dominant

    Correct Answer
    A. Guinea pigs get have of their traits from mom and half from dad. Some traits are recessive some are dominant
    Explanation
    Guinea pigs inherit half of their traits from their mother and half from their father. Some traits are dominant, meaning they are more likely to be expressed, while others are recessive, meaning they are less likely to be expressed. In this case, the black color trait is dominant, which is why there are more black guinea pigs than white guinea pigs in the litter. The specific traits of the parents do not matter, as nature decides which traits are expressed in the offspring.

    Mr. Potato Head has recessive homozygous traits, rr, and Mrs. Pototo Head have dominant heterozygous Rr lips.  What is the probability of the little spuds having their dad lips?

    • 1 out of 4

    • 50%

    • 25%

    • 3 out of 4

    Correct Answer
    A. 50%
    Explanation
    The probability of the little spuds having their dad's lips is 50%. This is because the dad, Mr. Potato Head, has recessive homozygous traits for lips (rr), while the mom, Mrs. Potato Head, has dominant heterozygous traits for lips (Rr). Since the dad can only pass on the recessive allele (r) to his offspring, and the mom can pass on either the dominant allele (R) or the recessive allele (r), there is a 50% chance that each offspring will inherit the dad's recessive allele for lips, resulting in them having their dad's lips.

    If one parent has widow’s peaks and the other has a widows peak what would be expect for their children?

    • The children will all have a widow's peak

    • None of the children will have a widow's peak

    • Half of the children will have a widow's peak

    • 75% of the children will hav a widow's peak

    Correct Answer
    A. The children will all have a widow's peak
    Explanation
    When both parents have a widow's peak, it means they both carry the dominant allele for this trait. Since the widow's peak is a dominant trait, all of their children will inherit at least one copy of the dominant allele from each parent. Therefore, all of their children will have a widow's peak.

    You are Gregor Mendel, interpret the following Punnett square to decipher sweet pea information.  - ProProfs

    You are Gregor Mendel, interpret the following Punnett square to decipher sweet pea information. 

    • 25% of the sweet peas are homozygous

    • There is a 1 in 4 chance for the sweet pea to be tall

    • 50% of the sweet peas will have the same genotype

    • The next generation of Tt sweet peas combining with Tt will all be tall

    Correct Answer
    A. 50% of the sweet peas will have the same genotype
    Explanation
    The Punnett square shows that 50% of the sweet peas will have the same genotype. This means that half of the sweet peas will have the genotype "Tt" and the other half will have a different genotype. The information provided in the question about the next generation of Tt sweet peas combining with Tt will all be tall is not relevant to the given answer.
